Commercial Elevator Counterweights

Mars Metal’s lead counterweights are ideal when seeking to increase the capacity of an existing elevator. Given that lead is approximately 45% denser than steel, it provides the necessary weight to counterbalance the new weight capacity. Mars Metal also manufactures steel counterweights according to the size and shape requirements of the client. Click here for more information about our commercial elevator counterweights.
